* files-x.el (modify-dir-local-variable): Handle dir-locals from
the cache, and from non-file sources.
* help-fns.el (describe-variable): Return consistent results when a
dir-local from a file came from the cache or did not. (Bug#8095)
If a dir-local has no associated file, say it came from a "directory".
